A Computer-based Model of Machine Operator Compartments.

The Bureau of Mines is developing a computer-based model of mining machine operator compartments to be used as both a research tool and as an aid to mining machine designers. Based on models now used in both the public and private sectors and on original software being developed by the Bureau, the model will perform reach assessment, visibility analysis, finite element analysis of canopy designs, illumination analysis (including both disability and discomfort glare ratings), and computation of an ingress-egress rating. The model will make extensive use of graphics to simplify data input and analysis. Two-dimensional orthographic projections of the machine and its operator compartment are digitized and the data rebuilt into a three-dimensional (3-d) representation. A 3-d mannequin is then used as the subject for the various analyses. Anthropometric data from either individual or any size population may be used. Outputs can be displayed both graphically and in a tabular form. In addition to its use in original machine design, the model should prove helpful as an accident investigation tool and for determining the effects machine modifications in the field will have on the critical areas of visibility and control reachability.
